Definitions
- the present invention relates to a gripper device which are provided in a plurality of numbers in a bag filling and packaging machine and moved, while holding the side edges of a bag, along a predetermined path and more particularly to a gripper device which, in the course of moving, changes a bag from a vertical orientation to a horizontal orientation or from a horizontal orientation to a vertical orientation.
- Patent Documents 1 to 3 discloses such gripper devices as described above,
- Patent Document 1 Japanese Patent Application Publication (Kokoku) Nos. H7-2490 (called “Patent Document 2”) includes (the numbers and letters in parentheses below are those given in Patent Document 1) a movable plate (3) fixed to a timing belt (2), a shaft member (5) rotatably installed on the moving plate (3), holding pieces (7) fixed to the shaft member, and a pair of gripper arms (gripping pieces G 1 and G 2 ) pivotally mounted on the holding piece.
- gripper devices are provided at equidistant spacing in between on the timing belt (2), which is wound around a pair of pulleys, and are intermittently moved (intermittently rotated) along a horizontal, racetrack shape path.
- the lengthwise direction of the shaft member (5) is set parallel to the path for the gripper devices, and the pair of gripper arms are provided so as to be pivotable over an angular range of 90° about the shaft member as the shaft member is rotated.
- each one the pair of gripper arms are pivoted symmetrically over a predetermined range to open and close in a plane parallel to the lengthwise direction of the shaft member (in the present specification, narrowing or widening the spacing between the (two or pair of) gripper arms to open or close (to pull taut) the bag mouth is referred to as “close” or “open” or as “open and close” or the like).
- empty bags are supplied to the gripper devices and held thereby and then the bags held by the gripper devices are subjected to various packaging steps, including opening of the bag mouth, filling of contents into the bag, sealing of the bag mouth, etc.
- a bag is supplied in a horizontal orientation to the gripper device, and in the bag mouth opening step, the pair of gripper arms pivots 90° to change the bag into a vertical orientation.
- Patent Document 3 The gripper device disclosed in Japanese Patent No. 3,753,930 (called “Patent Document 3”) includes (the numbers and letters in parentheses below are those given in Patent Document 3) a guide rod (31) fixed to an intermittently rotatable table (movable board (10)), a pair of gripper arms (arms 29, 29) fixed to a pair of sleeves (32, 32), respectively, which are slidably fitted to the guide rod (31), and a clamp (11) provided at the distal end of each one of the gripper arms so as to be pivoted about a main pin (43). These gripper devices are provided at equidistant spacing around the intermittently rotatable table and thus are intermittently moved (intermittently rotated) along a circular path.
- the lengthwise direction of the main pins is set to be parallel to the tangential direction of the path of the gripper devices, and thus the clamps are pivoted over an angular range of 90° about the main pins. Also, the pair of gripper arms are opened and closed by being moved symmetrically along the lengthwise direction of the guide rod.
- empty bags are supplied to the gripper devices and held thereby, and then the bags held by the gripper devices are subjected to various packaging processing, including opening of the bag mouth, filling of contents into the bag, sealing of the bag mouth, etc.
- the bags are supplied in a vertical orientation to the gripper devices and are changed to a horizontal orientation before the bag mouth opening step.
- the gripper arms themselves do not pivot, and only the clamps (11) provided at the distal ends of the gripper arms are pivoted about the main pins (43) over an angular range of 90°.
- the clamps have to be formed by relatively small parts, which are low in rigidity (strength) and have poor durability, and are prone to looseness brought about by wear of the rotating parts (the main pins (43)) and the like, making this configuration unsuitable to packaging heavy contents.
- Patent Document 3 discloses the opening and closing of pair of gripper arms, it does not disclose anything about adjustment of the reference spacing between a pair of (or two) gripper arms to accommodate bags of different widths.
- the present invention relates to an improvement in a gripper device used in a bag filling and packaging machine with which a bag can be changed, in the course of being moved, from a vertical orientation to a horizontal orientation or from a horizontal orientation to a vertical orientation, and it is an object of the present invention to provide a gripper device in which, when there is a change in the width of the bags to be processed, the reference spacing between a pair of (or two) gripper arms can be easily adjusted to be wider or narrower, and when a pair of gripper arms is opened or closed in the bag mouth opening step, etc., the movement distance of the gripper arms is adjusted easily, and further no such problems as insufficient rigidity, poor durability, etc. will occur in terms of the structure related to changing of orientation of the bags.
- a gripper device is provided in a bag filling and packaging machine in a plurality of numbers and moved along a predetermined path, and it changes in the course of moving along the predetermined path the attitude of a bag held by the gripper device from a vertical orientation to a horizontal orientation or from a horizontal orientation to a vertical orientation, and this gripper device comprises:
- the above-described bag orientation changing mechanism is comprised of a first cam lever that is pivotably supported by the movable frame and has a pivot axis which is parallel to the pivot axis of the pivot frame, a first cam roller that is rotatably installed at a free end of the first cam lever, and a first linking mechanism that links the first cam lever to the pivot frame.
- the first cam roller is in contact with the cam face of an orientation changing cam installed on the pedestal of a bag filling and packaging machine, so that the first cam roller is displaceable as the movable frame is moved along the predetermined path.
- the first linking mechanism has, for example, a first pivot arm, which pivots as the first cam roller is displaced, and a first linking rod, which is linked at one end thereof to the first pivot arm and at another end thereof to the pivot frame, so that the first pivot arm and the first linking rod form a toggle mechanism.
- the above-described gripper arm pivot mechanism is comprised of a second cam lever that is pivotably supported by the movable frame and has a pivot axis that is horizontal and in a plane which is perpendicular to the pivot axis of the pivot frame, a second cam roller that is rotatably installed at a free end of the second cam lever, and a second linking mechanism that links the second cam lever to one of the gripper arms.
- the second cam roller is in contact with the cam face of a gripper pivot cam which is shared by (or is commonly used for) all the gripper devices and is installed on the pedestal of a bag filling and packaging machine, so that the second cam roller is displaceable as the movable frame is moved along the predetermined path.
- a pair of gripper arms is installed on a pivot frame that is pivotably supported in a movable frame, and the pivot frame is pivoted for an angle of 90° so that the pair of gripper arms are pivoted up and down as a whole for an angle of 90°. Accordingly, problems such as poor durability or a lack of rigidity in the structure of the portion of a gripper device related to the changes in the orientation of bags can be avoided, and it is possible that the gripper device can be used for packaging relatively heavy contents.
- a gripper arm pivot mechanism that pivots a pair of gripper arms in symmetry to each other is provided. Accordingly, when the width of bags is changed, the reference spacing between the pair of gripper arms can be simultaneously and easily adjusted for all the gripper devices. In addition, the moving distance of the gripper arms, when opening and closing the pair of gripper arms in a bag mouth opening step, etc., can be easily and simultaneously adjusted for all the gripper devices.

- FIG. 8 is a perspective view (a portion of which is omitted) of the gripper arms in a downward orientation in another gripper device according to the present invention.
- a plurality of gripper devices are provided at equidistant spacing on the circumference of a circular table that rotates continuously or intermittently. As the table rotates intermittently, the gripper devices are moved intermittently along a predetermined circular path, bags are supplied to the gripper devices one by one in the course of this intermittent movement and held by the gripper devices, and then the bags held by the gripper devices are subjected to various kinds of packaging processing, including opening of the bag mouth, filling of the bag with its contents, sealing of the bag mouth, and so forth.
- a bag (empty bag) in a vertical orientation is supplied to the gripper device, and the side edges of the bag are clamped (held) by gripping members provided at distal ends of a pair of gripper arms of the gripper device, so that the bag is (as seen from FIG. 1 ) held in a vertical orientation (taking a hanging down state).
- a pair of suction cups approach the two sides of the bag, come into contact and stick to the sides, and then move away from each other by a predetermined distance to thus open the mouth of the bag.
- the pair of gripper arms are pivoted inward in a horizontal plane and moved to come closer (and the gap between gripper arms are narrowed), thus opening the mouth of the bag smoothly.
- the bag orientation changing step is performed while the gripper device are being moved between the bag mouth opening step position and the filling step position (described below).
- the pair of gripper arms are pivoted 90° downward to change from the horizontal orientation to a downward (vertical) orientation, thus changing the bag from its vertical orientation to a horizontal orientation (as seen from FIG. 2 ).
- the bag orientation changing step is next performed while the gripper device is being moved between the filling step position and a sealing step position (described below).
- the pair of gripper arms are pivoted 90° upward to change from the downward (vertical) orientation to a horizontal orientation, and the bag filled with the content is changed from the horizontal orientation to a vertical orientation.
- the gripper arms are pivoted outward in a horizontal plane and opened up (or moved away from each other) to widen the gap between them, so that the mouth of the filled bag held by the gripping members of the gripper arms is pulled taut to be closed. In this state, the bag mouth is clamped by a pair of hot plates and sealed.
- the gripping members of the gripper device are opened up, and the finished bag with the contents inside and its mouth sealed falls and is carried out of the bag filling and packaging machine.
- the gripper device is comprised of a movable frame 2 that is disposed on an intermittently rotating round table 1 , a pivot frame 3 that is pivotably supported by the movable frame 2 , and a pair of gripper arms 4 and 5 that are pivotably provided on the pivot frame 3 .
- the movable frame 2 includes a horizontal wall 2 a and a pair of vertical walls 2 b and 2 c .

- a bag of a narrower width is used than in the example of FIGS. 1 and 2 , and the lower portion 32 a and the higher portion 32 b of the gripper pivot cam 32 are installed at a higher height. Accordingly, the position of the second cam roller 25 is higher than in the example of FIGS. 1 and 2 , and the reference spacing between the gripper arms 4 and 5 (the spacing when the pair of gripper arms 4 and 5 are opened) is narrower, so that bags of a narrower width can be accommodated.
- the gripper arms 4 and 5 are in the horizontal orientation and in the open state.
- the bag F is supplied to the gripper device in a vertical orientation, and the side edges of the bag are clamped (held) by the gripping members 12 of the gripper arms 4 and 5 so that the bag F is held in a vertical orientation (a state of hanging down).

- the bag F is filled with the contents 33 (see FIG. 6 ).
- the first cam roller 17 passes through the area D (not shown) of the orientation changing cam 23 ; and in the course of this movement, the pivot frame 3 (and the pair of gripper arms 4 and 5 as well) are pivoted for 90° upward so as to be changed into a horizontal state, and thus the bag F (filled) held by the gripping members 12 is changed to a vertical orientation.
- the second cam roller 25 is located at the higher portion 32 b of the gripper pivot cam 32 , and the pair of gripper arms 4 and 5 remain closed. This state is shown in FIG. 6 .
- the first cam roller 17 is located in the area A of the orientation changing cam 23 , and the gripper arms 4 and 5 are thus in the horizontal orientation.

- the differences are as follows:
- first cam lever 16 a one of the pair of cam levers
- the other first cam lever 16 b the other one
- a larger-diameter gear 35 is fixed to the support shaft 19 a
- a smaller-diameter gear 36 that meshes with the larger-diameter gear 35 is fixed to the support shaft 19 b .
- the rotational angle of the support shaft 19 b is greater than the pivot angle of the first cam lever 16 a (and also than the rotational angle of the support shaft 19 a ).
- the support shaft 19 b is rotated 180° forward and reverse, and therefore the first pivot arm 21 is pivoted 180°.
- the first pivot arm 21 is provided only at one end of the support shaft 19 b.
- the first pivot arm 21 and the first linking rod 22 form a toggle mechanism.
- the first pivot arm 21 and the first linking rods 22 are in the vertical direction; and also, the axis passing through the center of the linking portion of the first pivot arm 21 and the first linking rod 22 (linking axis N 1 ), the axis passing through the center of the linking portion of the first linking rods 22 and the pivot frame 3 (linking axis N 2 ), and the pivot axis O 2 are all located within a single (common) vertical plane.
- This structure holds the horizontal state (see FIG. 7 ) and vertical state (see FIG. 8 ) of the pivot frame 3 .
- An orientation changing cam 23 that is shared by the gripper devices is provided in a horizontal plane on the pedestal of the rotary bag filling and packaging machine.

- the support shaft 19 b is accordingly rotated via the support shaft 19 a , the larger-diameter gear 35 , and the smaller-diameter gear 36 ; and as a result the first pivot arm 21 is pivoted upward (counter-clockwise in the FIG. 7 ).
- the first pivot arm 21 is pivoted 180° and comes into contact with the stopper 37 to stop its pivoting.
- the pivot frame 3 (and the pair of gripper arms 4 and 5 thereon) is pivoted 90° downward, the pivot frame 3 is changed to a vertical state, and gripper arms 4 and 5 face downward, so that the bag F held by the gripping members 12 of the gripper arms 4 and 5 is changed to a horizontal orientation (see FIG. 8 ).
- the holding action produced by the toggle mechanism is exerted on the first pivot arm 21 and the first linking rods 22 , so that the pivot frame 3 is held stably in the vertical state.
- the pivot frame 3 is changed from the vertical state (see FIG. 8 ) to a horizontal state (see FIG. 7 ).
- the first cam roller 17 is thus displaced, the first cam levers 16 a and 16 b are pivoted, and the support shaft 19 b is rotated via the support shaft 19 a , the large-diameter gear 35 , and the small-diameter gear 36 ; and as a result the first pivot arm 21 is pivoted 180° downward (clockwise in FIG. 8 ) and comes into contact with the stopper 38 to stop its pivoting (see FIG. 7 ).
- the pivot frame 3 (and the pair of gripper arms 4 and 5 thereon) is pivoted 90° upward, the pivot frame 3 is changed to a horizontal state, and the gripper arms 4 and 5 are changed to a horizontal orientation, so that the bag F held by the gripping members 12 of the gripper arms 4 and 5 is changed to a vertical orientation (see FIG. 7 ).
- the holding action produced by the toggle mechanism is exerted on the first pivot arm 21 and the first linking rods 22 , so that the pivot frame 3 is held stably in the horizontal state.
- the examples described above are those in which the gripper device of the present invention is applied to a particular rotary bag filling and packaging machine; however, the gripper device of the present invention is applicable to rotary bag filling and packaging machines in which different packaging processing is executed.
- the gripper device according to the present invention is further applicable to other types of bag filling and packaging machines as described below, for example.
- the rotary bag filling and packaging machine is of a type that makes intermittent rotation; however, the gripper device according to the present invention can be applied to a rotary bag filling and packaging machine of a continuous rotation type (in which the table rotates continuously at a constant speed).
- the movable frame is fixed to the rotary table (the movable frame thus is a separate part from the rotary table); however, the rotary table itself can be constituted by a movable frame (the movable frame and the rotary table are thus integrated).
- the gripper device according to the present invention is applicable to a racetrack type bag filling and packaging machine as disclosed in Patent Documents 1 and 2.
